Using this specific product
Loctite (Henkel) Epoxy Plastic Bonder is listed here as the Syringe (1:1) version for plastic, pvc, and household repair. For mixing and curing epoxy, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

How to check readiness
Check the coolest or thickest part for firmness before sanding, demolding or loading. Sets in 4 to 10 minutes; keep the bond supported for at least 10 minutes. Lift or move the item gently and avoid twisting the bond or pressing finished faces together. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.
Avoid this mistake
A larger batch can heat faster while a thin film may cure more slowly.
